When it comes to construction, there are many terms that are used interchangeably, such as “off-site construction”, “prefabrication”, and modular construction. These terms encompass a variety of different approaches and systems, from individual elements that are joined together using standard connections and interfaces to three-dimensional volumetric units with complete accessories. It can be confusing for those who are not familiar with the industry to understand the differences between these terms and how they relate to each other. Let's start by defining some of the key terms used in modular construction. Prefabricated construction refers to the process of manufacturing building components off-site in a specialized facility.
This is also known as external construction, which is essentially a synonym for prefabrication. On the other hand, modular construction involves building large modules off-site that are designed to be joined together. This is different from traditional construction, which is the most common form of construction where most of the work is done on site. Pole construction is an industrial term used to refer to traditional construction with wooden or metal structures. In practice, it is synonymous with traditional construction.
Kit construction, on the other hand, involves pre-cut parts that require significant assembly on site, but with minimal waste. Temporary buildings are structures that can be easily moved or dismantled and reassembled elsewhere. Panelized construction is a more efficient form of construction in which walls, floors, and other flat components arrive in large sections that can be quickly placed in place. Volumetric modular construction is the most complete form of modular construction, with a minimum amount of on-site assembly required. As an expert in the field with over 40 years of experience, I have seen firsthand how modular construction has evolved and improved over the years. At Triumph Modular, we have worked with homeowners, architects, and engineers to improve the design and performance of both temporary and permanent commercial building spaces. One of the key advantages of modular construction is the use of components.
These components are pre-manufactured off-site, which means that construction can continue without interruptions. This also allows for tailor-made solutions to be created for each project. To better understand the difference between prefab and modular kits, think of IKEA as a supplier of prefab kit furniture. Similarly, modular buildings are made up of more complete parts, making them easier to disassemble and transport to another location. Building systems is a general term used to describe any pre-designed construction method with predefined scope and configuration limits. The modules are individual sections of a modular building with enclosed functional spaces that can be joined with other modules to form a complete modular building. The generally accepted definition for volumetric modular construction is that more than 60% of the construction is completed off-site.
This means that the modules require less assembly and, therefore, even less on-site work, as each module fits into a predefined pattern.
